OPERATING INSTRUCTIONS
1. Output Voltage Adjustment:
Press the key [VSET] and then the value of voltage setting will be displayed on the voltage display; And the place setted flickers. Repress and the
Selected place of the setting values will be changed. And turn the knob and the setting value of the output voltage will be adjusted when the setted place flickers. Stop turning for a few seconds, then the setted place stops flickering and the power will return to the initial status.
2. Output Current Adjustment:
Press the key [ISET] and then the value of voltage setting will be displayed on the voltage display; And the place setted flickers. Repress and the selected place of the setting values will be changed. And turn the knob and the setting value of the output voltage will be adjusted when the setted place flickers. Stop turning for a few seconds, then the setted place stops flickering and the power will return to the initial status.
3. Over current protection:
Press the key [RECALL] and the storage direction will flicker. At this time, press [OUTPUT] and it will stop flickering, when the power is in the mode of
Over current protection; That is, the over current protection starts when the current is up to the setted value; Switch off the output voltage and the over current protection light [OCP] is on.
Eliminating the mode of the over current protection:
Press the key [RECALL] and the storage direction will flicker. At this time, press [OUTPUT] and it will stop flickering, when the power supplies will exit from the over current protection mode.
4. Storage Selection:
Press the key [STORE] and the storage direction light will flicker, which indicates the current storage data. Then press the key [Up-Arrow] and the next parameters of voltage and current can be selected; Press [Down-Arrow] and the previous parameters can be selected. In any storage direction, the relevant storage units can be stored when the parameters of voltage and current are setted.
5. Switching on or off the output:
Press the key [OUTPUT] and the output voltage will be switched on or off.
